Clean air filter

The air filter is directly related to the air intake of the engine when the car is running. The manager of Guangben dealership told the reporter that the air filter will not be blocked when the car is only driving in the urban area, but if the car is driving on dusty roads, it is necessary to pay special attention to the cleanliness of the air filter.

If the air filter is blocked or there is too much dust, the air inlet of the engine will be blocked, and a large amount of dust will enter the cylinder, which will accelerate the carbon deposition speed of the cylinder, which will hinder the ignition of the engine and cause insufficient power, and the fuel consumption of the vehicle will naturally increase.
